The Cape’s Beacon Hill delegation may be divided over the Cape Wind project, but not so the state’s 10 members of the U.S. House of Representatives.

From the Cape’s own Bill Keating to the far west’s John Olver, the reps asked Feb. 17 that U.S. Energy Secretary Steven Chu approve the company’s loan guarantee application with the Department of Energy to allow construction of the wind park in Nantucket Sound to begin soon.

Calling Cape Wind “innovative” and “poised to create jobs and kick start a whole new industry in the United States” in a joint letter, the congressmen wrote that the company’s long-term power contract with National Grid “will mean millions of dollars in savings to Massachusetts consumers” and that Cape Wind “will create over 1,000 jobs in Massachusetts… and has the strong support of organized labor.”

Other advantages highlighted are plans to build a marine commerce terminal in New Bedford to stage and assemble turbines as well as a manufacturing facility for the towers’ steel foundations.

“Cape Wind is the first U.S. offshore wind farm to secure all of its Federal, State and local permits,” the congressmen wrote.

The letter drew a sharp rebuke addressed to Keating by Audra Parker, president and CEO of the Alliance to Protect Nantucket Sound. She objected to the congressman supporting “massive federal subsidies for a project is so strongly opposed by so many of your constituents, that would force an extreme cost burden on ratepayers and taxpayers, that would result in a significant loss of jobs, and for which consensus, cost-effective alternatives already exist.”

Parker accused Keating of attempting to “seriously mislead the DOE, by misstating facts associated with this project and, in doing so, seek to induce the expenditure of hundreds of millions of federal tax dollars.”

In a Feb. 24 letter to Secretary Chu, Parker objected to claims that Cape Wind would reduce costs to consumers and noted that NStar chose not to buy the other half of the project’s power, opting for contracts with three other wind power companies “at less than half the cost of Cape Wind” and without annual escalator clauses.

Parker dismissed the congressmen’s job creation claims, asserting that almost all would be short-term construction jobs. She wrote that the project is still looking for governmental approvals, including the Construction and Operations Plan just released for public comment, which Parker said may require a supplemental Environmental Impact Statement.
